Title: Process for the manufacture of sodium carbonate of high bulk density
Inventor: BACH HEINZ
IPC: C01D7/40
Filed: 1961-06-12
Abstract: <PICT:0961051/C1/1> Compacted sodium carbonate with a bulk density of 0.8-1.6 kg/l. is produced by first removing trapped gases from calcined Na2CO3 produced by the ammonia-soda process and then compressing by mechanical pressure at 100-5,000 kg/cm.2. The removal of trapped gases may be accompanied by an initial compression of less than 100 kg/cm.2 by mechanical pressure.  H2O, e.g. 1/2 -2 mols/mol. Na2CO3 sprayed or as steam, soda lye, Na2SO4, Na salts of aliphatic fatty acids and/or fatty acid esters may be introduced during compression.  A roller type furnace R calcines Na2CO3 which is passed at 363-393 DEG  K. by conveyers C to funnel 1, via vibrating feeders 2 to profiled roller 3, is compressed at less than 100 kg/cm.2 by briquetting apparatus 4 and fed to cooling funnel 5.  The de-aerated Na2CO3 is fed to diagonal or triangular profiled rollers 6 where it is shaped and pressed.  The Na2CO3 is crushed and fed via collector 7 to screening drum 8 which grades it into fine, medium e.g. 0.2-1.5 mm., and coarse into bins 9.  The fine grade may be returned via worm feeds 10 and 13 and conveyer 12 to the input, while the coarse grade may be re-screened and passed down pipe 11 to funnel 5.

Title: Method of supplying current to high pressure metallic vapour arc lamps
IPC: H05B41/231
Filed: 1937-07-30
Abstract: 480,234. Supply systems for discharge lamps. EGYESULT IZZOLAMPA ES VILLAMOSSAGI R. T. July 30, 1937, No. 21130. Convention date, July 30, 1936. [Class 38 (iv)] A high-pressure metal-vapour arc lamp is supplied with short current impulses of several times the normal amplitude so as to alter the colour of the light emitted. The intervals between the impulses are several times longer than the duration of the impulses but the frequency is such that no flickering is present. The result may be attained by supplying the lamp from A.C. supply in parallel with a condenser and the parallel combination may be in series with a resistance. The condenser may be formed by the electrodes or the conductors of the lamp itself and in the latter case the conductors are brought close together and separated by dielectrics. The tube may be enclosed in an outer bulb and the series resistance may be arranged in the cap or in the bulb. The resistance may be an incandescent filament or it may be replaced by a condenser. Specification 344,439 is referred to.
Patent GB-1110845-A (GB)
Title: Process for the manufacture of cross-linked sulphochlorinated polyolefin filaments
IPC: D01F6/24
Filed: 1966-05-12
Abstract: A solution of a sulphochlorinated polyolefine is spun into a primary or secondary diamine or into a solution of a primary or a secondary diamine in a solvent which is miscible with the solvent of the spinning solution.  The polyolefine may be polyethylene, polypropylene, or an ethylene/propylene copolymer.  The polymer solvent may be an aromatic hydrocarbon, a light petroleum spirit, or a halogenated hydrocarbon such as chlorobenzene chloroform or carbon tetrachloride.  The last-named solvent is especially advantageous since the polyolefine is dissolved therein for sulphochlorination. The diamines (which cross-link the sulphochlorinated polyolefines) may be primary or secondary aliphatic, aromatic or araliphatic diamines, aliphatic diamines being used with special advantage. The carbon chain of the diamines may also be interrupted by bridging elements or groups such as oxygen or the carbonyl group. The amines which may be used include phenylenediamines, 4,41-diaminobenzophenone, xylylene diamine, the diaminodecanes, 2,21-diamino-diethyl ether, and N,N1-dimethyl-ethylene-diamine. Diamines having a chain of 2 to 6 carbon atoms are used with special advantage. In the preferred wet spinning process, the diamine solvent used for the coagulating bath may be a monohydric short-chain alcohol and/or a low molecular weight ketone.  The coagulating bath may contain a compound such as a tertiary amine or sodium bicarbonate to neutralize the hydrochloric acid formed by the reaction between the sulphochlorinated polyolefine and the diamine which takes place in the bath.  The filaments formed in the bath may be washed by passing them through a bath of hot water and stretched.

Title: Method of determining misalignment between two objects
IPC: G01R31/28
Filed: 1974-05-14
Abstract: 1429089 Determining contact misalignment INTERNATIONAL BUSINESS MACHINES CORP 14 May 1974 [28 June 1973] 21183/74 Heading H1K The invention relates to the manufacture of integrated circuits in which a contact pattern has to be applied through a mask placed in accurate alignment with existing features on a semi-conductor substrate and comprises a method of measuring the extent of any misalignment of the contact pattern. In a kerf area 16 of the substrate 10 is provided at least one resistive pattern 12 (e.g. diffused or comprising polycrystalline Si) with currentapplying contacts 52<SP>1</SP>, 54<SP>1</SP> and voltage probe contacts 60<SP>1</SP>, 62<SP>1</SP>, 641 thereon. When the contact pattern is correctly aligned vertically with the resistive pattern a further contact 24<SP>1</SP> is located precisely on the midpoint 28 between contactbearing arms 34, 38 of the resistive pattern 12. Incorrect alignment #L is determined by measuring, for a constant current between contacts 52<SP>1</SP>, 541 (pads 1 and 9), the potentials V1, V2 and V3 between pads 2-3, 3-4 and 4-5 respectively and using the relationship #L=(L(V1- V2))/(2V3), where L is the known length of the constant current path between arms 38 and 84 connected to pads 4 and 5. A second resistive pattern 14 enables horizontal misalignment to be measured. In a modification the misalignment of the centre-line between two contacts relative to a reference point on a resistive pattern is determined in a corresponding manner.

Filed: 1957-07-08
Abstract: 879,459. Feeding sheets. BACKHOUSE, H. T. June 30,1958 [July 8, 1957], No. 21545/57. Class 100(1) In sheet-feeding apparatus wherein sheets are fed in succession over a feed table to front lays and are slowed down as they approach the lays, the slow-down device is carried by an endless chain, band or like flexible element and projects upwardly above the table when travelling along with the upper run of the chain &c. The device is shown as applied to apparatus having a feed table formed of a number of longitudinal sections. Towards each side of the table there are two identical sections 10c each provided with slow-down devices. Each section 10c comprises two castings bolted together and supported on cross-bars 14, 15, 16, and in the cavity between the castings a gear 30, keyed on a continuously-rotating cross-shaft 31, drives a gear 32 provided with a cam 34 and a chain sprocket 33. Three slow-down hooks 41 carried by an endless chain 39 are mounted on two sprockets 38, 40, the sprocket 38 being integral with a sprocket 36 which is driven from the sprocket 33 by a chain 35. A roller 44 on a bellcrank 45, 46, which is rocked periodically by the cam 34, engages the top run of the chain 39 to cause the hooks 41 to follow the path above the table, indicated by arrows, to receive the oncoming sheets and slow them down. To allow these upward movements of the chain 39, the shaft 51 of the sprocket 38 is mounted eccentrically and urged in a clockwise direction by a spring 52 to maintain chain tension. The chain 39 and hooks 41 are driven at about half the speed of the oncoming sheets. In a modification, wherein the hooks 41 slow down from a speed more than half of the initial speed of the sheets to less than half that speed, an eccentric gear on the shaft 31 drives a gear coupled to the lower sprocket 33.
